Do one of the following:

To set up a password for the first time, turn on Password, enter your new password in the New password text box, and then reenter it in the Confirm password text box.

Tap Done to save your changes.

Tip

One more thing that you might want to do is to set a time limit for the screen time-out, which is the amount of time before your phone locks itself. To do this, tap Screen times out after and then select the time length you want.

If you've set a password yourself, you can choose the amount of
time that can pass before you're required to enter a password again after
you've done something on your phone, which can be anywhere from 30 seconds to
30 minutes, or never. If you have a Microsoft Exchange account through your
work, the Exchange administrator will set the options you can choose.

That time is different from how often your phone goes to sleep. You
can set that separately, but it can't be longer than the amount of time you've
chosen before requiring a password.

Here's how to change both options:

On Start, flick left to the App list, and then tap Settings > Lock + wallpaper.

Do one of the following:

To choose how often you want to require a password after doing something on your phone, tap Require a password after and choose the time you want.

To choose how often your phone goes to sleep, tap Screen times out after and choose the time you want.

important to you, like the time and date, or missed phone calls and new voice
mail messages, text messages, alarms, appointments, or emails.

the artist who's currently playing on your lock screen.

To change the wallpaper

On Start, flick left to go to the App list, and then tap Settings > Lock + wallpaper.

To get periodically updated images from Bing, tap Bing.

It depends on whether your employer requires a password for your
Exchange email account or you created a password voluntarily.

If your employer requires you to use a
password

Depending on your company's Exchange policy, your phone may reset to factory settings
or lock up and make you wait to get back in if you repeatedly enter an incorrect password. To prevent this from happening accidentally, if you enter the wrong password several times, your phone will prompt you to enter a special phrase to continue. Once you enter the phrase correctly, you'll have one more chance to enter your password correctly, or your phone will be reset.

Each company can choose from a variety of
settings for password requirements, so if you're not sure how to unlock your phone or avoid resetting it, you'll need to talk to the support person at your company who
manages your Exchange account.

Note

Some Exchange policies will reset your phone to factory settings
if you enter your password incorrectly a certain number of times. When your phone
resets, all personal data is erased.

If you created your own password
voluntarily

If you've entered the wrong password 5 times, the phone will be locked
for 1 minute. If you enter another wrong password, it'll be locked for 2 minutes,
then 4, then 8, and so on.

If you just aren't able to come up with the right password, you'll need
to reset your phone. Contact your mobile operator, check their website, or look
through your phone's documentation to learn how to do that.

Note

Resetting your phone may erase any personal content you have on
the phone, including music, videos, and apps that you've purchased through
Marketplace. It's a good idea to back up your information to your computer
periodically using the Zune software or Windows Phone app for Mac, but if you didn't
get a chance to do that before you need to reset your phone, your mobile
operator may be able to recover that info before you reset your phone. You can
contact your mobile operator for more details.
